2 Claims. 1i,

This invention has particular reference to a window stop "that will limit the extent to which a window may be opened to ,less than that permitting a person to enter, thereby to afford ventilation without danger of burglary. v

Object of the invention are to'provide a very simple and inexpensive butthoroughly reliable window stop of this kind that is convenient of installation; that is neat and attractive in appearance; that is very effective in preventing the window from beingfopened beyond a'certa'in distance; that cannot be rendered ineffective by tampering from the'outside, and that may be conveniently'placed ininefiective condition from the inside when it is desired to open the window further than is permitted by the stop.

As will hereinafter more fully appear, my improved window, stop prevents the raising of the lower sash, or the lowering of the upper sash, a distance great enough to permit a man to enter, while, on the other hand, it allows either or both of the sashes to be opened to any desired extent, within the range determined by the stop, 'for ventilating purposes Furthermore, the (device was created in responseto a demand for a ventilating stop that could not be rendered inoperative by. the insertionof a thin blade or other implement upwardly between the sashes.

Objects and advantages additional to those above mentioned will appear as:I proceed todescribe the'invention by reference to the accompanying drawing wherein like characters designate like parts in the several views.

In the drawing, Fig. 1 is a fragmentary elevational view of a window as observed from the inside, showing my improved stop attached to a stile of the upper sash, with the lower sash indicated in broken lines in a raised position; Fig. 2 is a vertical section through the part of the window shown in Fig. l, as observed from the right of the latter view, with the lower sash in full lines, and Figs. 3 and 4 are sectional details of my window stop taken on the respective lines 3-3 and 4-4 of Fig. 1, Fig. 4 being-drawn to a considerably enlarged scale.

I designates a mounting, which preferably consists of an elongated metal plate that may be economically produced from sheet metal, desirably in strip form of the required width in order to avoid unnecessary waste. Said mounting is provided with a central longitudinal slot 2 that is enlarged at its lower end to provide an entrance opening 3. The mounting is embossed about the slot 2 in such manner as to provide straight flanges along the opposite sides of the slot, and a curved flange 5 across the top thereof.

6 denotes a stud that is shown as cylindrical, and which has a circumferential. groove ladjacent one end, setting ofi afiat, relatively shallow circular head 8 that is joinedto the body of the stud by a neck 9.

Attached to the rear side of the lower end of the mounting l is a detent lfl that consists of a tongue of relatively thin spring metal, In the present instance, said detent is connected to the mounting by extending a thin eyelet-like flange or burr II, that is struck from the mounting in the punching of a hole at the lower end thereof,

through an aperture of the detent and peening said flange or burr over therebeyond, as cleafly shown in Fig. 4. The detentv II] is preformed,- as by means of a suitable die, to provide a forward deflection of its upper end within the recess formed by the embossing of the mounting about the slot 2.

, To install the device, it is only necessary to attach the mounting I to a stile 12 of the upper sash of .the window, with its lower end. adjacent the bottom rail 13, by suitable fastening means orscrews M, the marginal portion of the mounting being'punched at intervals for this purpose and the lowermost screw passing through the burred hole II. The head 8 of-the stud 6 may now be engaged through the opening 3, the detent Hi yielding rearwardly as the head enters.- The stud is then moved upwardly so that the flanges 4 enter the groove 1 to retain the head} against withdrawal through the slot. Thus connected to the mounting, the stud is permitted to travel within the slot 2 throughout the'length of the latter, excepting at the extreme lower end where the stud is stopped by engagement with the detent l0.

Accordingly, with the mounting attached to the window, and with the stud 6 movably connected to the mounting, both as above set forth, the lower sash may be raised or the upper sash lowered, or both, within the range of relative movement permitted by the stop. Therefore, the window may be readily adjusted for ventilating purposes, but any attempt to open the window beyond that permitted by the stop is prevented by the stud 6, when the latter reaches the upper end of the slot 2. In this position, the adjacent portions of the straight flanges 4 and the entire curved flange 5 occupy the groove 7 and insure a very strong connection between the stud and the mounting to eifectively resist force applied to either sash, in an attempt to open the window wide enough to permit a man to enter.

Obviously, it is impossible to disengage the stud S from the mounting I by means of an implement inserted upwardly between the two sashes; but when the window is closed, the stud 6 may readily be detached from inside the window by pressing the detent I'D rearwardly and sliding the stud downwardly until its head 8 withdraws through the opening 3.

While I have disclosed my improved window stop in the form presently preferred, changes and modifications may be made without departing from the spirit of the invention so long as they fall within the scope of the appendedzclaims.

Having thus described my invention, what I claim is:

1. A window stop comprising a mounting consisting of an elongated strip of sheet metal hav ing a central longitudinal slot that is enlarged at one end to provide. an entrance opening, .said mounting being embossed throughout the region of the slot to set off a flat marginal attaching flange and provide a guiding flange that occupies a-p'lane substantially ,parailel with and forwardly pf the plane of the attaching flange and that extends along opposite sides of the slot-and about the end thereof remote .from said opening, a stud that is cylindrical from end to end and is grooved circumferentially adjacent one of its ends to provide a head and a neck connecting the'hea'd to the body of the stud, the head of the stud being of asize to pass through the entrance opening and the neck having a thickness less than the width of the slot, the straight portions of the guiding flange on opposite sides of the slot occupying the groove of the stud when the stud is applied to the mounting to thereby detachably connect the stud to the mounting and provide the sole supporting means tor the stud, and a detent consisting of a leaf spring attached to the end of the mounting on the rear side thereof by a parto'f the mounting being peened over the detent, :saididetent extending across "the entrance opening so .as to normally prevent the head of the stud :from registering with said opening, the attaching flange being provided with holes for fastening means spaced apart about the mounting.

2. A window stop comprising a mount-mg consisting of an elongated strip of sheet metal having a central longitudinal :slot that is enlarged at one end to provide an entrance opening, said mounting being embossed throughout the region of the slot to set off a hat marginal attaching flange and provide a guiding flange that occupies a plane substantially parallel with and torwardly 4 of the plane of the attaching flange and that extends along opposite sides of the slot and about the end thereof remote from said opening, the attaching flange being provided with holes for fastening means spaced apart about the mounting and one of which holes is at the end of the mounting adjacent the entrance opening, the material about the last mentioned hole being projected rearwardly in the form of an eyeletlike flange, a stud that is cylindrical from end to end and is grooved circumferentially adjacent one of its ends to provide a head and a neck connecting the head to the body of the stud, the head of. the stud being of a size to pass through :the entrance opening and the neck hav- 1 ing a thickness .1655 than the width of the slot,

the straight portion of the guiding flange on opposite sides of the slot occupying the groove of the stud when the stud is applied to the mounting to thereby detachably connect the stud to the mounting and provide the sole supporting means for the stud, and a detent located on the rear side of the end of the mounting adjacent the entrance opening and extending across said opening so as to normally prevent the head of the stud from registering with said opening, the detent consisting of a leaf spring having an aperture through which the aforesaid eyeletlike flange is projected and beyondwhich it is peenedover to secure the detent to :the mounting, the ,detent beingpreformed to cause the end of the detent remote from said aperture to lie close to the guiding flange and to occupy the space provided by the embossing of the mounting whereby the detentfis held against turning.
